I appreciate your input. Perhaps I should have given a little more history on this gun.
Gun has a Valquartzen trigger, sear, sear spring and speed hammer, also the extracter and trigger shield.
I have polished the bolt and ramp with dremil tool. All seems to work together well and I have tried many types of ammo.
I did find two of my 5 mags to work consistantly. Now what can I do to correct the other three ruger mags that do not work? I have cleaned with carb cleaner and lightly oiled with gun oil...should a dry lube be used?...no lube?
Thanks again for your assistance. I will take a look at the flats on bolt again, double checking will not hurt.
